  1. Water Accounts in IsraelVienna January 2009 WATER AUTHORITY Dr. Or Goldfarb CENTRAL BUREAU of STATISTICS Zaur Ibragimov

  2. Recent Activities • Construction of the Database • Definition of the final reports • Data collection and updates • Developing a software interface for data update • Standardization of collected data

  3. Principles of the Database Construction • High resolution for variables, used for background calculation • Definition of algorithms for variables’ calculation by industries, suppliers and user sectors

  4. Methodology for the Database Construction Learning from: • Research and other countries’ experiences • Pilot of data collection • Cooperation with colleagues from IT Department (CBS)

  5. Construction Of The Algorithms for the Final ReportsSupply and Use of Water in the Economy Table 1: Supply of distributed water and of wastewater services Table 2: Use of distributed water and of wastewater services Table 3: Economic accounts for water distribution and wastewater collection industries Table 5: Physical flows of water corresponding to economic supply Table 6: Physical flows of water corresponding to economic uses

  6. Construction Of The Algorithms for the Final Reports Physical flows of water between the economy and the environment Table 7: Abstractions of water Table 8: Returns of water Table 9: Freshwater balance

  7. Construction Of The Algorithms for the Final Reports Physical flows of pollutants between the economy and the environment Table 10: Pollutant loads of freshwater abstracted for self and public supply Table 11: Pollutant loads of wastewater discharged to the sewage system Table 12: Pollutant loads of cooling and wastewater returned to the environment Table 13: Pollutant loads of cooling and wastewater returned to non-fresh sources

  8. Construction Of The Algorithms for the Final Reports • SEEA physical use table • SEEA physical supply table

  9. Construction Of The Algorithms for the Final ReportsAdditional reports according to special users’ requests • Use of water by suppliers and user sectors • Abstraction costs • Water prices • Data related to water consumption in municipalities • Allocation and use of water in agriculture

  10. Data sources • Water Authority • abstraction and useof waterby source, types and user sector • taxes paid by water abstractors • CBS • Municipalities’ data regarding economic variables • Production data by industry • Various Coefficients for calculated variables • Survey in the water and water related industries • Other government bureaus

  11. Data compilation: Related Activities • Pre-test survey • Update of the questionnaire according to the pre-test survey • Survey in the water and water related industries

  12. Survey in the water and water related industries • Sampling stratums : • water abstractors • reclamation plants • agricultural cooperatives • wastewater treatment plants • water and sewage corporations • The CBS Business Register was used as a framework for sampling

  13. Technological system • Developed software tools for updating the data • input forms for questionnaires • input forms for administrative files • Monitoring system for the incoming data • data qualitytests • cross-checking of data from different sources

  14. Technological system (continued) • Survey control tool • monitoring establishments’ reporting status • connecting documents delivery directly to the fax • updating of the data from different screens and with other systems in CBS
